Reaction Conditions

Reaction Steps

A solution of the above nitrile (0.20 g, 0.65 mmol) and nicotinoyl chloride hydrochloride (0.46 g, 2.6 mmol) in THF (6 mL) was then treated with DIPEA (0.56 mL, 3.2 mmol) and stirred at 80° C. for 16 h. The reaction was cooled to room temperature, concentrated under reduced pressure, diluted with CH2Cl2 (10 mL) and washed with brine solution (2×10 mL). The combined organic extracts were then dried (Na2SO4), filtered and concentrated and the crude material purified by flash column chromatography on silica gel (50:1:0.1 CH2Cl2/MeOH/NH4OH) to afford N-[(R)-1-(2-cyano-1-methyl-ethyl)-piperidin-4-yl]-N-(4-difluoromethoxy-phenyl)-nicotinamide as a pale yellow oil (104 mg, 39%).
